Announcement (2017-05-07): www.ruby-forum.com is now read-only since I
unfortunately do not have the time to support and maintain the forum any
more. Please see rubyonrails.org/community and ruby-lang.org/en/community
for other Rails- und Ruby-related community platforms.

A daily cronjob that does this:
1. creates a hotcopy of your subversion repository.
2. compresses the hotcopy.
3. uploads it to a ftp site.
4. notifies the admin about status.
I run this on an old P120 running openbsd,
it takes ~15 minutes to complete.
On my job I run it on a fast 2GHz box, where
it takes less than 5 seconds.
Changes:
* The FTP code has been refactored (now ~200 lines).
* Now it actual work on my own server.
